To address the issue of insufficient consideration of habitat factors such as fish habitats in current ecological flow research methods,this work choose the core protection area of the Yellow River Garden mouth carp core protection area as the research area.By taking the Yellow River carp as the research species,this work determined the ecological flow of the Yellow River carp based on the River 2D model of the coupling hydration model and the habitat model.Wa-ter depth and flow velocity are used as a limited factor for the protection of fish survival,and the depth and flow rate distribution of the water depth and flow rate under different flow conditions were obtained.In summary,the habitat model is used to simulate the appropriate habitat area of the Yellow River carp under different flows.The calculation results show that the minimum ecological flow of the carp in the garden mouth section is 230 m3/s,the minimum eco-logical flow of the growing period is 430 m3/s,and the minimum ecological flow during the wintering period is 150 m3/s.The calculation results can provide a useful reference for the protection of fish protection in the core fish protection area of the garden mouth and the ecological scheduling of the small waves of the Yellow River.
